Assessing Meteorological Variables, Larvae Free Rate and Dengue Incidence in Yogyakarta, Indonesia

Aims: Dengue is a disease closely related to the environment, including several climatic variables such as temperature, humidity, and wind speed. This research attempted to illustrate the relationship between dengue fever incidence and climatic factors, larva free rate (LFR) or Angka Bebas Jentik (ABJ) in Yogyakarta city, Indonesia.

Methodology: Secondary data from meteorological agency and district health office were collected and analyzed using Spearman Rank Test and Multiple Linear Regression Test.

Results: Temperature, air humidity and wind speed were associated with dengue incidence in Yogyakarta city during 2016-2018. Correlation between rainfall and dengue was r = 0.27 and p value = 0.11; temperature and dengue r =0.62 and p value = 0.000; humidity and dengue r=0.38 and p value 0.02; wind speed and dengue r=-0.36 and p value = 0.03; r = -0.36. Larvae free rate and dengue r=0.04 and p value = 0.77.

Conclusion: Climate variables are an important factor affecting the incidence of dengue fever. To decrease the incidence, it is necessary to educate the community on improving awareness related to the mosquito breeding place.
